Bosch Rexroth IndraDyn S MS2N - Vibration load during operation

5.4 Vibration load during operation
Vibrations are sine-wave oscillations in stationary use, which vary in their effect
on the resistance of the motors depending on their intensity.
The specified limit values are valid for frequencies of 10-2,000 Hz during stimula-
tion on the motor flange. Limitations can be necessary for occurring resonances
depending on the application and installation situation.
The following limit values apply according to EN 60068-2-6 for MS2N motors:

Check the vibration load on the fan housing in case of forced ventilation. The
specified values must not be exceeded.
